Study Notes
Milk Production Process
- Stages in milk production include milking, storage, processing, and distribution.
- The main protein found in milk is casein, which comprises about 80% of milk's protein content.
Milk Composition
- Water makes up approximately 87% of milk.
- Key minerals found in milk include calcium, potassium, and magnesium.
Milk Fat and Temperature
- The primary source of milk fat comes from the mammary glands of lactating animals.
- The recommended temperature for pasteurization of milk is typically around 72°C (161°F) for at least 15 seconds.
Milk Quality Indicators
- SCC stands for somatic cell count, a critical measure of milk quality and udder health.
- Factors contributing to variation in milk quality include genetics, feed, health, and milking practices.
Additional Milk Facts
- The normal composition of milk includes about 3.5% fat, 3.3% protein, 4.8% lactose, and essential vitamins and minerals.
- The shelf life of pasteurized milk is generally about 2-3 weeks when stored correctly.
Nutritional Value of Milk
- one glass of milk can fulfill about 15% of daily protein requirements for an average adult.
- Milk is 2-3 times more efficient at converting edible food into protein compared to other sources.
Environmental Efficiency
- Milk produces significantly more protein per unit of CO2 and land compared to crop-based protein sources.
- Humans have been consuming milk for approximately 10,000 years, originating from pastoral societies.
Milk Consumption Benefits
- The primary reason for consuming milk as a beverage is its nutritional value, providing essential nutrients and promoting bone health.
